11 Claims.

This invention relates in general to dispensers for liquid, particularlycarbonated beverages such as beer.

One of the objects of the invention is to provide a dispenser of thischaracter which makes it practical, convenient, economical and safe toutilize carbon dioxide for maintaining the proper carbonation of and theproper head of pressure on the beer. These advantages are realized tosuch an extent as to render the device available is provided and isequipped with a dispensing faucet. Surmounting the faucet and connectedwith the tap rod is a fitting which provides for the mounting of a gageand for the support and connection to the tap rod of a cartridge orholder for a supply of gas under pressure. In the releasable connectionprovided between the discharge nipple of the cartridge and the fitting,novel features are embodied which provide for hermetic sealing of theconnection and also for the automatic undersetting of the valve in thedischarge nipple of the cartridge. The discharge nipple of the cartridgeand the associated parts are protected against breakage or theapplication of excessive strain by a suitable guard which takes the formof a tubular structure telescoped over the adjacent vend of thecartridge, interconnecting with the-fitting and straddling theconnection and the nipple.

l Other objects and advantages reside in lcertain novel features of theconstruction, arrangement and combination of parts, which will behereinafter more fully described and particularly pointed out in theappended claims, reference` being had to the accompanying drawing,forming a part of this specification, and in which:

Figure 1 is a view partly in transverse vertical section and partly inside elevation showing a dispenser embodying the present invention;

Figure 2 is a similar view on a reduced scale showing the dispenser inuse; and

Figure v3 is a fragmentary sectional view on an enlarged scale showingdetails of the construction of the connection between the dischargenipple and the fitting.

Referring to the drawing, the numeral I designates a tap rod in ltheform of a metal tube closed at its lower end as at 2 and, provided withopenings 3 adjacent its closed lowerend.

To the upper portion of the tap rod a faucet 3 is provided andpreferably embodies substantially the construction shown in my pending`application filed January 12, 1934, Serial No. 706,347.

Into the upper end of the tube I, a fitting 4 is secured. This fittinghas an opening 5 extending longitudinally therethrough. The lower end ofthe opening 5 is connected with the upper end of a gas tube 6 whichextends down through the tap 5 rod for a portion of its length and thenextends laterally out through the wall of the tap rod as indicated atl.'I'he upper end of the fitting 4 and the parts associated therewithprovides a connection between the fitting and the discharge nip- 10 ple8 of a holder or cartridge 9 for carbon dioxide gas. In the structureshown, the fitting 4 has a reduced extension I0 threaded into thelowerend of a guard designated at II. The upper portion of this guard isenlarged as at I2 and telescopes 15 over the lower end of the cartridge9 to provide a positive connection between the holder 9 and the fitting4, which positive protective connection is independent of the nipple 8and of the means associated therewith to provide a hermetic seal. 20 Forinstance, if the cartridge 9 is struck or pushed forcibly the strainwill be taken by the guard I2 and the fitting 4, the nipple 8 beingrelieved of strain.

In the upper end of the longitudinal opening of the fitting 4 a sealingcup or bushing I5 is threaded and is provided with an annular flange I6,which flange with the cup I5 affords a seat for a sealing disc or washerI l of rubber. A valve trip I8 has one end secured in the opening of thebushing I5 and projects up through the opening in the disc Il. Thislvalve trip pin has a restricted opening therethrough and the opening iseven Afurther restricted at its upper end. The purpose of the pin I8 isto lift the valve I9 provided in the discharge nipple 20 away from itsseat 2l and against the action of its spring 22 thereby allowing fluidunder pressure to escape from the nipple 8.

From the foregoing, it will be obvious that when the nipple 8 isthreaded down into the internally threaded portion 23 of the guard thelower end of the nipple will be brought against the top surface of thesealing disc I1 and pressing the same withinA the flange I6 andeffecting sealing engagement between the sealing disc and flange and pinI8. When the nipple is screwed down sufliciently the pin I8 engages thelower end of the valve I9 and presses it upwardly and away from its seatso that pressure may flow past 50 the valve through the annular space 24to the interstice between the engaged metal surfaces of the valve I9 andpin I8. These surfaces while engaged are not so constituted or machinedas to prevent the pressure from flowing in between them and then inthrough the pin I8 down through the opening 5 of the iitting to the gastube 6. sion 25 provided with an opening 26 communieating with theopening 5. At the outer end of the extension the opening 26 communicateswith oppositely extending transverse openings 21 and 28.y rA gage 29 hasits connecting member 30 threaded into the opening 21. A relief valve 3|is connected to the opening 21, the valve comprising a vented housing32, a valve 33 normally engaged with the valve seat 34 under theinfluence of the action of a spring 35 exerted through a follower 36.

The .bushing I5 has a depending nipple 40 thereon which receives theopen end 4I of a rubber check valve, the rubber check valve beingclamped on the nipple by a ferrule 42 and having a longitudinal slit 43therein designed to permit of passage of the gas under pressureoutwardly therethrough but to prevent inward passage of pressure.

While I have shown and described one construction in which the inventionmay be embodied, it is to be understood that the construction shown hasbeen selected merely for the purpose of illustration or example and thatvarious changes in the size, shape and arrangement of the parts may bemade without departing from the spirit of the invention or the scope ofthe subjoined claims.
